Direct to diff outrunner conversion*update*

if that is a 4 pole out runner, see if your esc has 30 degree timming, that should fix your cogging issue

Not sure if the quark has that kind of adjustability, I will check.

Probably need to do the heatsink mod the the 65 as it appears to be comming of the thermal tape. Any reason why I can't delete the case entirely and just epaoxy a heatsink to the fets and maybe put it in a little box like the MM? Or maybe shrink it like a bk esc?

Outrunners are usually 12 pole designs, otherwise, there would be no point to using them in place of inrunner (low pole motors).

Okay, a Power 60 motor (400kv) on 5s2p A123, or better yet 4s lipo (lower top speed) should be just about right for a maxx or Revo truck.

Top speed would be around 48mph with 5s2p A123, or 45mph on 4s lipo.

OR, on the extreme torque end... the Power 110 (295kv) on 5s lipo or 6s2p A123 for a little over 45mph, and crazy, crazy torque... that would be a silent, deadly machine.

Yeah, my setup with the 46 on 4s lipo would be around 40mph. My only issue would be lack of a slipper for an off road vehicle, and you would need a good slolid motor mount, like 1/4" 7075 al. I was also thinking that i could incorporate two revo slippers, one on each end of the motor. a custom shaft and adapters to replace the spurs with drive cups would be required. Might add too much length though. If you really want one, I may be able to get a discount, not sure how much but give me the #s you want and I can ask my buddy. Looks like the 46 would be about 80-85 bucks from him.

Hey Lincpimp,

How do you plan on going shaft to shaft with a slipper? If you get that figured out, would you post some pictures please? I've been tossing that around in my head for awhile now, and so far I've come up with nothing.

Before you go paying a wad of money for something that IMO is overpriced. Check out what Lucien has to offer over at http://www.innov8tivedesigns.com/ind...cPath=21_25_38

I'm not sure what length you're looking for, but he has some things that you might be interested in.

I have a 3032-12 that should be here by Thursday. I'm going to test it in my E maxx Direct Drive setup. But soon, I will be doing an E Revo Direct Drive to Diff with a motor similiar to this. The E Revo will probably have to wait on his 40mm motors, which are supposed to be out next month.

Yes, I think the 40mm can would be a better choice, more torque. I like the ring bearing idea, should provide more support for the rear of the can. His prices are good, I will wait on some spec for the 40mm cans and maybe try one out.

No pics yet on the slipper, just ideas in my head. if you are familiar with how the revo slipper works, my idea was to setup each end of the motor shaft with the crosspin hole and a threaded portion for the slipper lock nut. That would allow the main portion of the slipper to mount to the motor. I would then have to come up with some sort of adapter to replace the spur gear. This would have a 5mm (or whatever size needed) extension on it to mount a drive cup to. My only problem is trying to keep the overall length to minimum, and a method to access the slipper adjustment nut. At the moment my adapter looks like a hat that will sit over the end of the slipper nut and mount to the slipper hub with the three screws that usually hold the spur gear. Only problem is that hat covers the nut, requiring removal to adjust the slipper. I could make legs that mount to the slipper and thus leave some room to get a small wrench to the nut, but I think that there would not be enough space b/t the legs to access the nut. I think it would be pretty good having two slippers, as one could be adjusted to give more slip (rear) to aid in cornering traction, etc...

I hope Lucien doesn't mind me quoting him, but he already sent me some of the anticipated specs for the 40mm motors. I'll pass that information on to you.

"Initial plans for the 40mm motors are to have 4 frame sizes. There will be a 4020, 4025, 4035 and 4045 size motor. The 4020 and 4025 will basically be larger versions of the 3008 and 3014 size motors. The 4035 and 4045 will be made a little different, and will have an additional ring bearing that supports the back end of the motor's flux ring. This is done to stabilize the motor, and prevent flexing of the motor shaft under load. I have attached a photo that shows the rear end of a 4045 motor to show this bearing.

The approximate power ratings on the motors and the weights will be as follows:

4020 - 1200 watts, 280 grams, 9.88 ounces
4025 - 1500 watts, 328 grams, 11.57 ounces
4035 - 2000 watts, 488 grams, 17.21 ounces
4045 - 2500 watts, 585 grams, 20.64 ounces

There will be at least 3 different Kv's for each motor, and there may be 4-5 versions of the 4020 size. I have a set of 14 prototypes in the 40mm size right now and they are currently wound with the following Kv numbers, but this is subject to change once the final versions are decided upon.

4020-8 ....... 1000 Kv
4020-10 ....... 786 Kv
4020-12 ....... 701 Kv
4020-14 ....... 591 Kv
4020-16 ....... 526 Kv

4025-10 ....... 631 Kv
4025-12 ....... 565 Kv
4025-16 ....... 422 Kv

4035-10 ....... 446 Kv
4035-12 ....... 386 Kv
4035-14 ....... 328 Kv

4045-10 ....... 381 Kv
4045-12 ....... 315 Kv
4045-14 ....... 272 Kv

Hopefully that answers all of your questions.

The new 30mm outrunner that I'm getting has the endbell bearing also. They are upgrading that line as well.

On the slipper idea, Is there a way to use a thrust bearing on the driveshaft and just control spring tension by how just pressure is on the bearing? Then make both sides of the clutch material stationary? This would move the adjustment to a more external location. The Thrust bearing would have to have a Spring Loaded housing with a "track".
Hmmmm, I'm still processing on this one. Let me read your post a few more times. LOL
